Flu. Seasonal flu is very common viral infection with symptoms you have described. Usually the condition resolves on its own with home care. Drink water and get a good rest. NSAIDs (e.g. Aleve) are also recommended every 6 hours. If concerned, see your PCP after 4 days or so. Take this opportunity and quit smoking. .
